I still have some doubts about your setup.
You have a 2 ports hdmi module in the panasonic.
So how do tell the BS3 to use the right slot/port?
Normaly a DVI module is used in slot 1 and the RS232 port sends the signal to "scan" the slot for video.
But now in this slot there are 2 ports, so probably extra input is needed from the BS3.
About the 24fps. Correct me if I'm wrong.The source which produces the 24fps video is connected to the BS3.
Can the BS3 handle these 24fps videosignals? Does it already have a "pass through"?
Normally the BS3 does the scaling and the panel functions only as a monitor. So does it need a 24fps handling?
As I've seen in the BV9 service manual, the DVI has 4 seperate data streams, which all are used. At first sight the hdmi doesn't have all these signals. So why use hdmi if DVI suits the job? (I thought the PF10 series has a DVI input as standard? But it seems not?)
